You are very welcome and thank you for your kind words. Video arriving soon on getting big data with the cdsapi ... Don't forget to subscribe to get notifications of new uploads 😊
very nice and detailed explanation. Thank you so much. I feel so happy as I found your video. It is really helpful. hope to see videos on atmospheric moisture tracking (backward).
I appreciate your help professor, its clear and precise presentation. After this video my work is easy. If you can please upload a video for how to down load COSMIC satellite data from UCAR in the .nc format? thank you
Hi thanks for the useful video, after downloading the data in NetCDF form is it possible to convert the NETCDF file into the raster image, or tiff file for each hour. one tiff file for each hour. thanks
Very detailed explanation !! Thank you so much!! It's the first time I work with ERA5 reanalysis. Question: Exists a limited quantity of download times? Something like you just can download whatever information from Copernicus "cds" a limited times?
No you can ask for the same data repeatedly. If you don't have much local storage this is helpful. Just retrieve when you need... Thanks for the nice feedback
I forgot to mention that there is a data limit however. That's why it is useful to learn the API so you can download data in loops. See my other videos to learn how to do this
Very useful video! Congratulations and many thanks. I've been working with single and pressure levels ERA5 data since last year. More recently, I've been trying to download model level data from MARS servers with the aim of having more tropospheric level information. Do you work with these data? In my experience, it takes a long time downloading for a single site.
Yes I've worked with MARS a lot, in fact, exclusively before the CDS came out, and especially as I worked in the RD section of ecmwf for 7 years before moving to ICTP (the 5 phase prognostic cloud scheme was my last development for the model before leaving). You are correct that model level data takes a lot of time, is a lot of data! Probably better to download a region and then extract single sites offline in CDO. The other option is to try out the toolbox, although I'm not a big fan since the caching wasn't working too well last time i tried.
7:07 You said you are going to show how to aggregate the hourly data to daily data. I have not seen that video. Can you please make a video about this? Much appreciated!
Hi, this vide is very useful, I have a question about the mean wave period. Would you know if this parameter is the same as the mean energy period from this reanalysis dataset? Thank you :)
There is a playlist, but sometimes the videos are a bit out of order. When I have completed the last 5 for my new online edX course I promise I'll take the time to order them carefully in the playlist... 🙂
@@climateunboxed Thank you!! I asked because this video was so helpful and clear. If you have an edX course, I'll enroll in that one. Meanwhile, I've been watching your other videos relevant to me.
@@anjalichandra9646 you are very welcome... I need to finish a couple more videos before I can launch the eDX course... on ENSO indices, correlation mapping, and making functions... when they are done I'll finish the course. I'll post details here, it should have UNESCO certification I hope; that's the idea in any case... Please don't forget to subscribe and pass the word! :-)
@@MultiRose86 not quite :-( I'm sorry, I've been working hard on it and other overdue deadlines over the Christmas break... I'll try to update next week - I promise as soon as the beta version is ready to post it here.
HI sir, I want to download the ERA5 reanalysis global data from 1950 to present.when I trying to download the data it shows data is too large reduce your selection.Then I selected only 10 years but it takes more than 4 hours to download. Is there any other way to get the large data from ERA5. Thank you sir.
You are attempting to download huge datasets and I'm afraid that this will take time. One thing you can consider is to cut down the region to the area of your interest. This can reduce data volumes by an order of magnitude or more... Good luck!
Could I ask what application you use to view the data? I am using a Mac and continuously get an alert stating I do not have the appropriate application to view the ERA5 download. I am trying to assess the ERA5 monthly wind data for context. Thanks!
thank you very much Sir. Is there any way to extend ERA 5 monthly average data on pressure levels from 1979 to present backwards to 1969? My need to get the data starts at 1969.
YES! :-) there is a beta-release back extension now to 1950, it is available in a separate link while under going evaluation : cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-pressure-levels-monthly-means-preliminary-back-extension?tab=overview I hope that helps, and please spread the word about the channel - Recently I've been buried with a heavy teaching load and paper deadlines, but I will be uploading new material soon...
@@climateunboxed Thank you sir. I wish the extension data is just connected to the previous one that ends at 1979. Sure, this channel will be spread by me to my colleagues and I believe it will grow soon. It would be helpful too if you can teach us students the typical analysis that specifically targeting sectoral level. E.g. If I know the coping range of temperature for survival for crop A, then what type of climate analysis should I do to the temperature change in model data (say, present and future data), to detect any significant changes to the survival temp of this particular crop?. In the other words, should we present the information at different risk levels for the decision makers? This is what i called from climate science to services and is still missing from my perspective. A TH-cam video on such would be very very useful. Sorry for my mouthful :)
@@Rainstorm121 Very soon there will be a new video on masking, which is extremely relevant for calculating changes in risk for e.g. certain crops. I will try to finish it before the end of May. Thank you for your kind words and feedback!
@@climateunboxed thanks you very much in advance Sir. I really look forward for that. Highly appreciate that and would like to learn more from your video contents.
Hi Lee. sorry, somehow i missed this reply. At the moment while this remains beta you need to do a separate download and then merge with cdo mergetime . Regarding your second question regarding surviving temperature, basically this is a question of threshold exceedance and I have a video now in the pipeline for this which I will release soon. The frequency statistics will need this new video combined with my temporal statistics video. If you subscribe hopefully you should get a notification when the masking video is published soon. Best wishes and thank you for the great feedback
For over 5 hours i have been searching for an instructional material on how to download data from Copernicus, finally I found this, the very best.
great :-) thanks for your kind words! much appreciated
Thank you very much for great lesson. Today is my first day and will continue learning your lessons..Thanks again.

That's a tricky one, I'd need to do that in python... Thanks for the suggestion though, I'll think about it...
thank you very much, it's very kind of you

Thanks for sharing.
Many thanks

How can I download NDVI AWV data from ERA5
I have a problem with mandatory filed, how can i do with this?
Hi, this vide is very useful, I have a question about the mean wave period. Would you know if this parameter is the same as the mean energy period from this reanalysis dataset? Thank you :)
Ooo that one I don't know. I'll ask a friend at ecmwf and try to get back to you
@@climateunboxed thank you!
Can anyone tell me what he means by "last lecture?" If there is a complete course, I would like to watch it in order.

Can you please provide the link for the edx course
i will do as soon as it is ready, start of January
The edX Course is launched (releasing sections over the following weeks) - openedx.ictp.it/ "climate data analysis"
hello sir, I hope you are well.
please I need your help to download air quality data. Can you give me your email. Thank you very much.
